After the above code is executed, date will refer to
a new Date instance. Furthermore, that Date
instance is mapped to the "NOW" key in the map.

Note that LazyMap is not synchronized and is not thread-safe.
If you wish to use this map from multiple threads concurrently, you must use
appropriate synchronization. The simplest approach is to wrap this map
using Collections.synchronizedMap(Map). This class may throw
exceptions when accessed by concurrent threads without synchronization.
